Source: Table 2-2, Bay Area Air Quality Management District, CEQA Air Quality Guidelines, May 2017 (BAAQMD 2017b). Project-Specific Impacts FCS conducted an Air Quality and Greenhouse Gas Emissions and Energy Impacts Constraints Analysis for the project (included as Appendix AQ). FCS’ analysis involved running the California Emissions Estimator Model (CalEEMod) version 2020.4.0 based on applicant-provided information and comparing the CalEEMod outputs to BAAQMD thresholds. a. Would the project conflict with or obstruct implementation of the applicable air quality plan? Federal and State air quality laws require air districts to create air quality improvement plans that describes how the jurisdiction will meet air quality standards. Under State law, these plans must be updated every three years. The most recently adopted air quality plan in the Bay Area is the 2017 Clean Air Plan (2017 Plan). The 2017 Plan is a roadmap showing how the San Francisco Bay Area will achieve compliance with the state standard for atmospheric ozone levels over a one-hour period as expeditiously as practicable, and how the region will reduce transport of ozone and ozone precursors to neighboring air basins. The 2017 Plan does not include control measures that apply directly to individual development projects. Instead, the control strategy includes stationary-source control measures to be implemented through the BAAQMD regulations; mobile-source control measures to be implemented through incentive programs and other activities; and transportation control measures to be implemented through transportation programs in cooperation with the Metropolitan Transportation Commission, local governments, transit agencies, and others. The 2017 Plan also represents the Bay Area’s most recent triennial assessment of the region’s strategy to attain the state one-hour ozone standard. Under BAAQMD’s methodology, a determination of consistency with the most recently adopted Climate Action Plan (CAP) should demonstrate that a project protects air quality and health at the regional and local scale and protects the climate. Any project that would not support these goals would not be considered consistent with the 2017 Plan. On an individual project basis, consistency with BAAQMD quantitative thresholds is interpreted to be that it supports for the 2017 Plan goals. The 2017 Plan is based on anticipated population and growth estimates included in the General Plan; as long as the project is included within the population and growth estimates, it would be consistent with the 2017 Plan. The project would involve construction of 18 residential units on an infill site, consistent with the goals of the General Plan regarding strategic growth; therefore, the project is consistent with population and growth projections (City of San Leandro 2016a). The project would not generate emissions exceeding those anticipated by the General Plan EIR (discussed further in items b and c), and therefore, the project would not conflict with CAP goals.
